All toads are frogs, but not all frogs are toads. Both belong to the order Anura, but toads are a subset of frogs. They can usually be identified by their dry, bumpy appearance, but there are some frogs that look a lot like toads, and there are many toads that look wet and slimy like a frog. If you’re ever unsure, just go with ‘frog,’ and you’ll always be correct. Source Source 2 Source 3
